Difficulty (1-10): 5
Use Orlandu to get some quick hard hits on Dycedarg. Try not to hit Zalbag, but if you have to, he's not crucial. You might want to steal Dycedarg's sword, the Defender, because it's attack power is higher than a Rune Blade, and the evade is higher. In any case, you should be able to make short work of Dycedarg.
